Tips. 1  Full-grown Chihuahuas generally don't get to be above 6 to 9 inches tall. 2  If yours is taller than that, either as a puppy or an adult, he may be a mixed breed. 3  Don't use color as an indication of your dog's breed, as both short-and long-haired Chihuahuas can come in practically any color.

Factors Affecting Wave Speed. The speed of any wave depends upon the properties of the medium through which the wave is traveling. Typically there are two essential types of properties that affect wave speed - inertial properties and elastic properties.
As you might expect, the difference in wave speed has a profound influence on the nature of seismograms. Since the travel time of a wave is equal to the distance the wave has traveled, divided by the average speed the wave moved during the transit, we expect that the fastest waves arrive at a seismometer first.
